Currently, there is no OEM Performance Brake Kit for the 335i!
However, I have high hopes that we will get one very soon judging from the F30 335i official images:
Those are 4-pot calipers in the front of a 335i MSport package:
So, I have high hopes that those will be a direct swap for the E90 335i. I am checking every 2 weeks in realoem.com to see when they will add the F30 parts catalog!
